Has the power of the Games prompted you to make a difference in your life or the lives of others?

London 2012 is seeking people from across London and the UK with a story to tell for a new film and will be holding casting sessions over the next couple of weeks.

From the worthy to the wacky, we want to hear from people who have made a difference – however large or small - whether it’s through sport, culture or education.

It could be making a difference in the local community by setting up a sports club for young people, overcoming a disability to take part in extreme sports, learning to play the piano at the age of 70, or even climbing Everest – London 2012 would like to hear your story.

If successful at the casting, your story could be featured in London 2012’s film which will form a crucial part of promoting the London 2012 Olympic Games and Paralympic Games.
